When deciding on which type of memory module to add, which of the following considerations are FALSE?

A.
You can use Error-Correcting Code (ECC) and non-ECC memory modules interchangeably.

B.
If your server boards are designed specifically for use with ECC memory modules, you cannot mix ECC memory modules with non-ECC memory modules.

C.
If your server boards are designed for use with non-ECC modules, you could install ECC memory modules because there is a possibility that it might work.

D.
None of the above

Explanation:
The recommendation is to NOT use ECC and non-ECC memory modules interchangeably. This is because of the chipset installed on the server board indicating the use of one memory module or the other.

Incorrect
Answers:
B, C: The rules for using ECC and non-ECC memory modules are simple: If your server boards are designed specifically for use with ECC memory modules, you cannot mix ECC memory modules with non-ECC memory modules. You should always avoid situations that require mixing of ECC and non-ECC memory modules. However, if your server boards are designed for use with non-ECC modules, you could install ECC memory modules because there is a possibility that it might work.
D: The recommendation is to NOT use ECC and non-ECC memory modules interchangeably. This is because of the chipset installed on the server board indicating the use of one memory module or the other.
